SAFETY-RAZOR.

Specification of Letters Patent. I Patented. June 1, 1920,

Application filed September 19, 1919. Serial No. 324,942.

To all whom it may concern: Be it known that I, AUGUSTUS H. BRrAN'r,

a citizen of the United States, and a resldent of Glen Ridge, in the county of Essex and State of New Jersey, have invented. a new and useful Safety-Razor, of which the fol-, lowing is a full, clear, and exact description.

This invention relates to safety razors and particularly to an improved holder adapted to receive blades of the type disclosed 1n my Patent No. 1,309,456, issued July 8, 1919, and has for an object to provide an improvedconstruction wherein the blade may be placed in position and removed without danger of injuring the edge thereof. Another object of the invention is to provide a holder for a thin blade which will expose the entire length of the cutting edge of the blade and which will hold said cutting edge firmly along a predetermined line in respect to the holder.

A still further object more specifically is the provision of a holder or head for a safety razor blade which is formed comparatively thin'and compact and with all of the resilient or spring members formed as integral parts of the head.

In the accompanying drawing v Figure 1 is a front elevation of the safety razor with the blade removed and the parts shown in an openposition. I

Fig. 2 is a top plan view of the construction shown in Fig. 1. r a

Fig. 9 is a view similar to Fig.7 showing the parts closed and the blade in place.

Fig. 10 is a front and edge view of the blade capable of use with the holders shownin Figs. 1 and 6.

In the construction of safety razors heretofore heads have been formed .to hold the blade in place for producing a cutting operation, and various means have been utilized for, correctly positioning the blade in the holder. In addition springs have been connected with certain parts of the head for preventing any loose motion of the blade,

but these springs have not fully and satisfactorily accomplished their object unless adjusted Very carefully and accurately. This adjustment is expensive and often times is disturbed before the razor com'esinto use. In addition enlargements or projections have been provided for receiving a handle and springs for clamping the upper part of the holder against the blade.

In. the present invention it is aimed screwed or riveted into a depressed portion- 2 in the bottom plate 3 of the head. The plate 3 is substantially flat and is providedwith guard fingers 4 near one edge of subtantially the usual form, but preferably connected by a connecting bar section 5. Adjacent the opposite edge of plate 3 are a pair of hinge knuckles 6 adjacent each end of the central projection 7 arranged therebetween, said projection being slightly bent for receiving the bent over spring extension 8 formed as an integral part of the top 9. The plate 3 is in addition provided with upstanding stopsflO and 11 having substantially square shoulders 12 and 13 for receiving the projecting ends of the blade 14 shown in Fig. 10, said blade. being formed according to my patent abovereferred to.

to overcome these various objections and also The top plate 9. is preferably slightly curved as illustrated in Fig. 3 and is pro-. vided with overlapping flanges 15 and 16 which overlap the stops 10 and 11, and with ears 17 and 18 which overlap the end knuckles 6 so as to produce a finished appearance and cover the pintles 19, these pintles, two in number, being screwed into I the respective end knuckles as illustrated in Fig. 1. Arranged on the back edge of the top plate 9 are hinge knuckles-20 and 21 pressed without producing any additional,

adapted to fit between the frespective knuckles 60f plate 3 so as to accommodate the respective pintles 19. On each slde of the main spring 8 and spaced slightly theremovement. of the blade, and consequently the blade will be held firmly in position with the' cutting edge thereof approximately above the center of the series of up-loops 24 of the guard 4. By positioning the blade in this manner and holding the same firmly in place the blade is the first thing which strikes the face when the device is lIl'llSQ and there will be a cutting or shaving ac tion for the full length of the blade, asthere are no obstructions in the way.

- The arrangement of the spring. arms 22 and 23 and the main spring 8, as illustrated in Fig. 5, prevents any accidental d slocation or molestation of the adjustment, so thatthe top plate 9 snaps firmly into position agalnst the blade when closed, and the spring arms also press at spacedpointsagainst the. back of the blade. The spring arms are usually made slightly longer than necessary to force the projecting ends of the blade against the over.

shoulders 12 and 13, but this extra length is merely pressed. or bowed back and acts in the double capacity of holding the blade more firmly in place and as an insurance against not contacting with the back of the blade.

In manufacturing and setting up the parts the plates -3 and 9 are stamped out and formed to appear as shown in Fig. 5, eXcept that the ears 17 and 18 are not yet turned into place after the knuckles 20 and 21 and the various knuckles 6 have been interlocked.

The ears 17 and 18 are then bent over and polished if desired. This completes the assembling of the head. When the device is to be used the end flanges 15 and 16. are grasped and the top plate 9 swung to an open position as shown for instance in Fig. .3, the blade 14 is then placed in position fiatwiseagainst the plate 3, or if desired it .may be placed loosely and 'flatwiseagainst the top plate 9 after which the top plate is hinged over and the blade will fall automatically into place. During the closing action of the top plate 9 the spring 8 will pass what may be termed dead center and will urge the plate to a closed position as shown in Fig. 4.

The pintles or pins 19 are screwed back of blade 14 and move the blade until it presses tightly against the shoulders 12 and 13. It will be noted that the blade 14 isv not slid fiatwise over the plate 3, but is laid fiatwise against the same, the movement being in a direction normal to the face of said plate whereby the cutting edge will not touch any part of the head.

' In Figs. 6 to 9 inclusive will be seen another or second form of the invention in which the barrels 6 are bent upwardly instead of downwardly as shown in Fig. 5, while a central extension 25 is provided somewhat similar to extension 7, but coacts with a spring extension 26 which is at an obtuse angle from the body part of the back 9, which back is preferably straight instead of arc-shaped. The front edge of the back plate 9 is slightly curved at 27 so as to press against the blade 14 near the front edge. In this form of the invention,

as well as the form shown'in Fig. 5, the spring for closing the top plate 9' is made.

from part of the head instead of an extra 1 spring, but insteadof using the extension from the plate 9 as the sole, or almost the sole spring action both the projections 25 and 26 act as spring members, which will, in a certain sense, lock the plate 9 open and lock the same closed. In addition, instead of forming the spring arms 21 and 22 with rather long projections, spring or resilient eccentrics 28 and 29 are provided which gradually force over the blade 14 until it presses tight against the shoulders 12 and 13. In case the arc of the eccentric cam is too large the resilient feature will take care of the extra size and consequently the cam will be compressed or brought under tension, though it will not be sufiiciently strong to in any way overcome the action of the main spring 26. If a. true solid eccentric was provided the blade would be pushed overagainst the shoulders 12 and 13, but

the eccentric would have to be absolutely true and also the back of the blade would.

have to be absolutely true to secure good results. However, by providing a resilient eccentric cam any unusual size or inaccuracies will be taken up by the resilient action of the spring features of the eccentrics.
